With the above structure, when the screw driver operates in the forward direction, the guide part 211 is disposed at one end of the forward thread groove 221, the driving motor 23 drives the driving screw 22 to rotate in the forward direction, and at the same time, the motor 242 operates to make the sliding seat 241 move in the same direction as the guide part 211, and when the first temporary holding groove 223 is reached, the spring 248 for forward pushing is compressed, and the elastic force of the spring 248 pushes the second vertical part 253 to make the guide part 211 leave the first temporary holding groove 223 and enter the next thread section of the forward thread groove 221; when the guide part 211 leaves the first temporary ring groove 223 and enters the next thread section of the forward thread groove 221, the first gear 244 is engaged with a first tooth group 2461 on the first rack 246, at this time, the second gear 245 is in an idle running state, so that the running speed of the sliding base 241 is lower than the running speed of the guide part 211, the spring 248 for forward pushing gradually returns to a normal length, when the spring 248 for forward pushing returns to the normal length, the second gear 245 is engaged with a second tooth group 2471 on the second rack 247, at this time, the first gear 244 becomes an idle running state, the running speed of the sliding base 241 is higher than the running speed of the guide part 211, the spring 248 for forward pushing is gradually compressed again until the guide part 211 enters the second temporary ring groove 223, the guide part 211 is pushed out by the spring 248 for forward pushing into the next thread section after the temporary ring groove 223 for a while continuing the reverse running of the drive screw shaft 22, and the principle of the reverse running of the motor 242 is not repeated. In the above process, only the motor 242 and the driving screw 22 need to operate at a constant speed, and the control is convenient.
The intermittent motion mechanism 2 further comprises a travel switch 26, and the travel switch 26 is arranged on both sides of the operation travel of the moving seat 21. The motor 242 and the travel switch 26 are both connected to the controller, and when the travel switch 26 generates a trigger signal, the controller immediately controls the motor 242 to rotate in reverse and rotate at a preset rotation speed upon receiving the trigger signal, so that the movable base 21 and the sliding base 241 can synchronously perform forward and reverse travel switching.
In the automatic medicine packaging system, the mechanical arms positioned on the two sides of the packaging device can unload all medicine bottles on the medicine bottle carrying platform at one time and load new medicine bottles, the medicine bottle carrying platform passes through the medicine charging device in a reciprocating mode, and the two mechanical arms can load and unload the medicine bottles in turn, so that high-efficiency loading and unloading can be realized, and the packaging efficiency is improved.
